Define Variable Example.pkt
This example shows a simple curb.
- The Height variable is set to 5.
- The Width variable is set to 3.
- P2 is drawn from P1 at a Delta Y value of Height divided by 3.
- P3 is drawn from P2 at a Delta X value of Width and a Delta Y value of Height.
- P4 is drawn from P3 at a Delta X value of Width divided by 2.
- P5 is drawn from P4 at a Delta Y value of negative Height, plus the negative Y value of P2.
- The shape is closed with L5, and a shape is added.
Note: To test the condition, in the example, change the Preview Value of the target surface.
